Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

Why Hollis Air Duct Cleaning Is Castaic’s Preferred Air Duct Cleaning Company
We’ve been serving the Santa Clarita Valley since 2004, and Castaic’s particular conditions, fine Mojave silt, Angeles National Forest wildfire ash, and canyon winds that drive debris deep into duct systems, are exactly why we invested in negative-air equipment from Nikro and rotary brush systems from Rotobrush. Our technicians are background-checked, uniformed, and held to The Garrison Code: arrive inside the quoted window, price in writing, complete the job by the book, and leave the site clean.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues. Every job carries our 365-Day Done Right Promise in writing: if the work fails within a year, we return and make it right at no charge, including a free second visit.
Vent Cleaning in Castaic
Vent Cleaning in Castaic means more than wiping registers. The supply vents in your living spaces and the return grilles that pull air back to the handler both collect the fine dust, pollen, and ash that canyon winds push through your home. We use rotary brush agitation under controlled negative pressure to dislodge debris from each vent run, then extract it with HEPA filtration so nothing resetstles in your rooms.
A typical residential vent cleaning in Castaic runs $180 – $340 for a standard tract home with 8 – 12 vents. Ranch properties with extended runs or outbuilding vents may run higher, and we price those in writing after inspection.
Supply Vent Deep Cleaning
Supply vents push conditioned air into your rooms. In Castaic, they often show a ring of fine silt around the diffuser where Mojave dust settles after the system cycles off. We remove each cover, brush the duct throat, and verify airflow with a smoke pencil before we leave.
Return Vent and Grille Service
Return vents pull air back to the handler and are the first collection point for airborne debris. Homes near unpaved roads or open land in Castaic see heavier loading here. We clean the grille, the boot, and the first several feet of duct where debris concentrates.
Air Duct Repair in Castaic
Air Duct Repair in Castaic addresses the sagging, disconnected, or rodent-damaged ductwork that is common in the area’s 1980s – 2000s housing stock. The original flexible ducts in Hasley Canyon and Hillcrest attics were never designed to last thirty-plus years in temperature swings and wind-driven dust. We inspect with video cameras, then repair or replace sections using mastic-sealed connections and proper support strapping.
Most air duct repairs in Castaic fall between $250 – $580 depending on accessibility and the extent of damage. Full section replacement in tight attics runs toward the higher end. We write the price before we cut anything.
Flex Duct Reconnection and Support
Sagging flex duct crushes airflow and creates debris traps. In Castaic’s older tract homes, we often find ducts that have pulled free from plenums or collapsed onto attic insulation. We rehang with proper straps and reconnect with mechanical fasteners and mastic, not tape that dries out in attic heat.
Leak Sealing and Mastic Application
Even intact ducts leak at joints. We pressurize the system, locate leaks with smoke or theatrical fog, then seal with duct mastic. In Castaic’s dusty environment, sealed ducts keep your filter doing its job instead of letting the attic pull debris past it.
Trusted Brands We Service in Castaic
Our crews carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, the same tools commercial HVAC contractors use, not hardware-store attachments. For filtration upgrades, we stock Honeywell, Aprilaire, and Guardsman products with fast turnaround for Castaic customers. If your system needs a media filter upgrade after cleaning, we can usually install it the same visit.
Common Air Duct Cleaning Problems We See in Castaic Homes
- Wildfire ash loading in blower motors and return ducts. After Santa Ana wind events or Angeles National Forest fires, we find a distinct gray film on blower wheels and inside return plenums that standard suburban dust cycles don’t produce. This ash is fine enough to pass through cheap filters and recirculate until it’s professionally removed.
- Sagging original flex duct in Hasley Canyon and Hillcrest attics. The 1980s – 2000s tract homes in these neighborhoods often have flex duct that has collapsed onto insulation or formed low points where debris collects. Camera inspection reveals what a register check cannot.
- Extended duct runs on rural properties loading with pollen and dust. Ranch homes off the paved roads have longer supply and return paths, often to outbuildings or guest quarters. These runs see heavier pollen and road dust, and they need agitation tools that reach the full length, not just vacuum wands at the nearest register.
- Vacuum-only “cleaning” that leaves Mojave silt caked on surfaces. Without rotary brush agitation and negative-air containment, fine silt adheres to duct walls and blower components. We see this residue in systems “cleaned” by competitors who never established proper pressure differential or used mechanical agitation.
Pricing for Air Duct Cleaning in Castaic, CA
Whole-home air duct cleaning in Castaic typically runs $350 – $650 for a standard residential system with 8 – 15 vents. Commercial systems or large ranch properties with extended runs start around $800 and scale with duct footage and access difficulty.

What moves the price: number of vents and returns, attic accessibility, whether the system needs video inspection first, and any repair work we find. We do not quote per-vent teaser prices that balloon at the door. The price is written down before we start, and it does not move.

FAQs About Air Duct Cleaning in Castaic
Every 2 – 3 years for most Castaic homes, versus 3 – 5 years in less wind-exposed Santa Clarita suburbs. Castaic’s canyon winds, unpaved road dust, and wildfire ash load ducts faster. Homes near open land or with wood heat may need annual inspection. Call (361) 326-5060 and we’ll assess your specific conditions.
Yes. Extended duct runs to outbuildings and heavier pollen and road dust loading mean we bring longer hose sets and plan for additional agitation time. We inspect the full system with video before quoting, so the price reflects actual footage, not a standard room count. Call (361) 326-5060 to schedule.
Check your filter first, it will load rapidly. Then schedule a blower motor and return duct inspection. We commonly find ash coating on blower wheels and inside return plenums after major events, and standard filter changes won’t remove it. Call (361) 326-5060 for post-fire system assessment.
Usually worth inspecting. Original flex duct in Hasley Canyon and Hillcrest often sags or disconnects after decades in attic heat. We camera-inspect first. If the duct is intact, we clean it. If it’s crushed, torn, or rodent-damaged, we quote repair or replacement in writing before cutting anything. Call (361) 326-5060 to book inspection.
Yes. We clean duct and dryer vent runs to guest houses, workshops, and barn conversions, pricing by actual footage and access. These systems are often neglected and load heavily with dust and pollen. Call (361) 326-5060 for a written quote on your full property.
